Trek Powerfly FS 4 G2 2020 Full Suspension Electric Mountain Bike

The 2020 Trek Powerfly FS 4 G2 Electric Mountain Bike is the gateway to more adventurous trail riding. Full suspension enables you to maximise the potential of Bosch pedal assist by soaking up the rugged terrain so you can enjoy a smooth ride.

Powerfly 4 now comes with the same battery system as all of Trek’s more high end Powerfly models. the RIB Removal Integrated Battery system not only looks super sleek but is also super use friendly. The battery is fully hidden inside the frame to protect it from damage and wear and is easy to remove for charging and storage without the use of tools. It also enables you to mount a bottle cage on the downtube even on full suspension bikes.

Powerfly FS 4 features high end electric components from Bosch paired with the capability of a 130mm trail bike with the same frame and suspension technology refined over Trek’s long trail riding heritage. The Purion controller has a Walk Assist mode, and a variable intelligent eMTB mode that automatically delivers the optimum power assist depending on your terrain. 130mm of travel, a 10 speed drivetrain with a wide range cassette and powerful pedal assist up to 25kph will allow you to take on more rugged trails in comfort with confidence.
